feat(C++): String detection is performed using SIMD techniques (#1720)

## What does this PR do?
ref: https://arxiv.org/pdf/1902.08318.pdf
ref: https://github.com/simdutf/simdutf
I learned about the related simd technology, as well as this paper and
project implementation.
Using SIMD technique for string detection.
First, I need to implement the logic and complete the latin character
detection
``` c++
// Baseline implementation
bool isLatin_Baseline(const std::string& str) {
    for (char c : str) {
        if (static_cast<unsigned char>(c) >= 128) {
            return false;
        }
    }
    return true;
}
```

Then, I tried to use SSE2 to speed it up, which is obviously a little
bit faster, the logic is to read multiple characters at once and then do
the bit arithmetic
Obviously, there was a speed boost, but I didn't think it was enough, so
I tried it again with AVX2

I think in terms of efficiency, it's already much faster than before. 
But how do you prove that it's also logically true?
I added test samples to verify

``` C++
TEST(StringUtilTest, TestIsLatinLogic)
```

Finally, I ran the test

done.
